Application filed February23, 1909. Serial No. 479,615.

T 0 all whom it may concern:

Be it known that I, J osErH B. STRAUSS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Windows, of which the following is a' specification.

This invention relates to improvements in windows, and has for its object to produce an improved construction of this description.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a view of a. window embodying the invention; Fig. 2 is a vertical sectional view through the window shown in Fig. 1; ig. 3 is an enlarged sectional view on line 33 of Fig. 1; Fig. 4 is a sectional view taken on line 4.4 of Fig. 5; Fig. 5 is an enlarged sectional view through the pinions and racks; Fig. 6 is a vertical sectional view through the side ofa car showing a window embodying the invention.

Like numerals refer to like parts throughout the several figures.

Referring to Figs. 1 to 5 inclusive, there is shown a construction particularly adapted to be used in buildings. In this construction there are two elements or sashes 1, 2, arranged in the same plane. The element 1 is provided with a rack 3 which, as shown in Fig. 5, forms a portion. of the sash. This rack engages a pinion 4; mounted on the shaft 5, carried by a stationary part at the side of the window. As shown in Fig. 5, the rack 3 is an integral piece, having two parallel parts in different planes connected by a connecting web, the parallel parts proj ecting in opposite directions from the web, one attached to the element 1 and the other having teeth so as to engage the pinion a. The element 2 has connected with it a rack 6 which engages a pinion 7 mounted on the shaft 5. This shaft 5 has at its other end two similar pinions 8 and 9 for the adjoining window. A spring-pressed latch 10 engages one of the pinions, as forexample, the pinion 41-, having a part which projects between its teeth thus holding the pinion against movement. This latch can be rocked about its pivot so as to release the pinion when it is desired to move the window. The pinions 4 and 7, it will be noted are at right angles to the window sash; that is the axis of rotation of these pinions is parallel to the plane of the window. The two sections positively in the other direction by means of the racks and pinions. The element 1, when.

the window is opened, is moved down into the receiving pocket 11.

Connected with the element 1 is a water shedding device which prevents water from flowing into the receiving pocket 11. This water shedding device may be constructed in various ways. As herein shown the bottom frame 12 of the window is hollow and has at the outer surface an opening 13. Connected with the part 12 is a pivoted piece 14 which extends entirely across the window and which is preferably provided with a curved face as shown. This piece has one or more lugs 15 projecting from it by means of which it is pivoted to the bottom part of the frame. When the window is up or in its closed position, the part let rests upon the sill or stationary part 16, and hence it will be seen that any water due to rain or the like that strikes the window will pass along the curved face of the part 1 1 and then to the slanting face 17 of the stationary part 16, and will not pass into the pocket 11 or to the inside of the window. When the sash l is lowered, the part 1-1 is automatically moved up into the receiving space 18 in the bottom part of the sash and hence does not interfere with the movement into the receiving pocket. There may also be associated with the sash 1 a cinder guard consisting of a piece 19 having a curved face 20 and resting upon the top face of the bottom sash piece (see Fig. This piece 19 may be provided with projecting parts which engage grooves 21 in the sash. When the sash is lowered into the receiving pocket the part 19 strikes the part 16 and slides along the grooves 21, thus keeping ,closed the pocket 11, when the window is completely opened or only partly opened. This cinder guard construction is particularly adapted for windows on railway cars. When this form of window is applied to buildings Where the top of the window on one floor comes near the ceiling, the upper sash 2 (see Fig. 2) may be provided with a pocket 22 located at the side of the pocket 11 for the lower sash of the window on the next floor. In Fig. 2 this construction is formed by providing a diaphragm 23 in the pocket 11, so as to divide it into two sections as it were. This diaphragm may be of metal and also acts as a fire protection as it prevents a draft from the lower apartment to the upper.

In Fig. 2 I have also shown another means for arranging the window when there is not suflicient room below the ceiling for the upper section. In this construction there is a third section 2%, pivoted at 25, and placed so as to be out of the plane of section 2. This section 24: may be opened by moving it about itspivot. In this figure I have also shown means for automatically closing the windows in case of fire. This is done by means of a weight 26 hung above the upper section 2 by means of a fuse 27. If there is a fire in the vicinity, the fuse becomes heated and releases the weight 26 which drops upon the upper section 2. These sections are balanced and the weight is such as to easily cause them to move to close the window. If the sections are of different sizes as shown in this figure, the smaller sections are provided with a counterweight to produce a balancing condition.

In Fig. 6 I have shown a construction to be applied to a car. There are two sections 36 and 37 placed side by side forming a double window. Each of these sections is provided with a rack 38 and there is a pinion 39 which engages both of these racks.

As shown in this drawing, when either of the sections is moved, section 37 moves up into the receiving pocket 43 and the section 36 down into the receiving pocket 42. In this construction it will be seen that when the two sashes are partially moved they still overlap each other and keep the opening closed so as to prevent drafts from coming in upon the passengers, and also prevent dust and cinders from coming in, and yet permit ventilation between the two sashes, the air coming in in the space between the bottom of the outside sash and the glass of the inside sash and then passing up between the sashes and entering the car in the space between the upper'part of the inside sash and the glass of the outside sash. As shown in Fig. 5 there is provided what may be called a pinion with two pitch diameters, one rack engaging the smaller pitch diameter and the other rack engaging the larger pitch diameter. There may also be provided a weighted rack 40 having fastened to it a counterweight 41 which works into a guide 4:4:- This construction may be provided when the two sections are of different weight so as'to equalize the weight, and balance the parts.

In Fig. 2, thecontrolling device which is applied to one section of the window to produce the movement of the other is the weight 26, while in Fig. 1 it is the electric motor 55.

I claim: i f

1. A window comprising two elements adapted to be moved to open and close the window, a unitary combined rack and frame for each of said elements, a rack piece parallel to said frame piece, an intermediate piece at an angle to the frame piece and rack piece and integral with both of said pieces and a pinion adapted to engage said rack piece.

2. A window sash comprising a metal sash frame, a projecting part at right angles thereto and integral therewith, a lateral pro jecting rack part connected with said projecting part and provided with rack teeth, said lateral projecting rack part being in a plane different from the sash frame but parallel thereto.

3. A window comprising a metal sash frame made up of a thin sheet 'of metal bent so as to form three sections, one section acting as the glass support, another section parallel thereto acting as a rack and an intermediate section connecting the other two sections.
